- l NEW YORK, N. Y.. A coRroRAToNor DELAWARE j cAsT'ERY MouNTING MEANS This invention relates i to ,l castery mounting means and 'has particular referenceto 1mproved means for anchoringgthev caster or a.

caster element 'on the end ofthe legof anA article of furniture orthe like.y y l l VIhe objects ofthe invention are to provide `meansv for` eifectively anchoring a caster"` or a caster element on the endv of a `furniture or'like. leg; to provi-de, means for anchoring i the part as an incidenttothe normal opera-j tionof mounting the caster element kon the V'p 'As' clearly shown leg; to provide means suchvasl above referred to which can be manufactured cheaply and economically, and in-gener'al, it is'the object of lmyinvention to4 provide an improved caster mounting. means such as above referred to.f- Other objects and advantages Will beV understood `by reference to thefollowing `.20` specification and accompanying drawingsv wherein I have described and illustrated' mounting means 'of the type Vreferred lto, as applied to a casterl socket. n l

In the'drawings: y. 'f j Fig. -1 is a sectional 'view ofthelower end of a leg having acasterV mounted therein through theagency of a caster socket' whlch embodies a selectedk form ofmy-present' invention.` t l Y e Y so Fig.' 2 is a lan of thecaster socket.

Fig. 4 is a diagrammatic side elevation of a part of the caster socket illustratlngthe 35 manner in which the same isrk anchored in the le. .f 1 Referring now 'toL then drawings, I` have yin-Y dicated 'in Fig. e, 1 aQwooden furniture 'leg 5 v having a bore k6 .Which receives a cas'tersocket 7 ,thelatter being adapted toremovably and swivelly receive acasterxS'of convenf.

In the embodiment "oflmy'invention herein disclosed, my `invention 'concerns only the Sermeans for anchoring, moregorless perma- 1'929. serialA No. 379.376.

vnently,the'socketelement 7 inthe leg5.,V As i i shown, the'socket element 7 includes a tubularv part 9 which is provicledvwth'a bottom plate 10 anchored to the tubular member at the lower end ofthe latter in any suitabley manner. The bottom plate 10, inthe present" instance, is circularv in formfand isr providedl around its periphery with a laterally'up- Wardly extending'flange l1 which terminates i .upwardlyy extending teeth ory Vin aplurality of rongs12. y e f in Fig. 3, the prongs 12 are `arranged in pairs, one pair of which includes prongs such as 13 vandl4. LThe ref- 'f v if i spective prongs of each/pair are spaced Vapart as indicated at 15, the adjacent faces of theprOngs Vbeingy preferably substantially parallel as shown. -The outer or remote faces or edgesofthe prongsfof each pair are 'i oppositely inclined as indicated at 16 and 17. The bottom plate and rits prongs are made of sufficientlyductile metal so that when the'prongs are drivenendwise into'the yend of the leg, the oppositelyinclined `faces '16 and 17 will serve tokdeflect the prongs in opposite directions (towards eachother) as s clearly indicatedjin Fig. 4. In the'l said Fig.y t 4, the normalor initial'position ofthe prongs vis indicated in broken lines, and the deiiected, -f

operative position ofthe prongs is indicated Vin full lines. y Itwill ybe seen that the deflect-l ed prongs serve to form, in effect, a dove tail."

interlocking connection between the bottom ,plate of thesocket and the furniture leg.

Thefabove described form of anchoringv of caster sockets as well as to the'casterjelement, fork instance gliding ycaster buttons,

the spirit of my invention, the scope of which should be determined by. reference to the .fol-i lowing claim', construingthe sameas broadly means is obviouslyV applicable to lother types anolgI'am aware Vthat changes may. be made Yinthe arrangementvof the "prongs and their inclined portions so as to obtain substantially v the same result but without departing vfrom l (lll as possible consistent with the state of the art.

I claim as my invention:

A caster element having a plurality of prongs adapted to be driven endwise into a furniture leg, or the like, said prongs being arranged in pairs having oppostely inclined outer edge portions and substantially parallel inner edge portions, whereby, when the prongs are driven into the leg, the prongs of each pair aredeflected towards each other so as to ormTineHeet, a dove-tail interloolring connection between Jthe leg and the castel' A n element.
